LAND-RECLAIIVIING DOCK.

SPECIFICATION forming part of Letters Patent No. 7 02,627, dated J une17, 1902.

i Application tiled October 5, 1901. Sorial'No. 77,647. (No model.)

T0 all whom t may concern..-

Beit known that I, EPHRAIEM CHAQUETTE, a citizen ofthe United States,and a resident of New Rochelle, county of Westchester, State of NewYork, (whose post-oflice address is 63 Mechanic street, New Rochelle,)have invented certain new and useful Improvements in Land-ReclaimingDocks, of which the following is a specification.

The object of my invention is to provide a oatable apparatus or dockwhich can be moored or anchored conveniently near the marsh low land, orother locality to be reclaimed, and which shall be adapted to receive-from scows or other receptacles the mud and other materials dredged upfrom bays, rivers, and other bodies of water and to deposit the `same.upon the locality to be reclaimed. l

One application of my invention is shown in the accompanying drawings,in which- Figure l is an end elevation. Fig. 2 is a cross-section. Fig.3-is a top plan. is a longitudinal section. showing the bottom of thereceiving-vats.

Same letters indicate similar parts in the different figures.

A is the frame or body of the dock, containing the waterway B. This dockis made of substantial material and of sufficient size to admit a scowsuch as -is generallyemployed in connection with harbor-dredges forreceiving the mud and other substances raised by the dredge. This dockis designed to be moored as near as possible to the shore adjacent tothe land to be reclaimed, but is to be sunk to such depth that therewill be water enough in the waterway B to-ioat the mudscows or othervess'elsfrom which filling material is to be received.` This willordinarily require a depth of some :liftee'nifeet of water in thewaterway B. That part o f the dock` which is immediately'below theWaterway is divided into akconvenient number of vats orreceiving-troughs C, the sides lof which taper inwardly downward to'form a trough, which said trough also inclines downwardly toward thepumping side of thedock. By means of ythis construction the contents ofthe vats are v the dock is provided with an engine D, which Figp/J.'Fig. 5 is a detail' 'a time.

convenient construction and are to bev located'at such places in thedock as is found mostv convenient.

A series of rotary pumps G G is provided, one for each of the vats C,from, which it sucks out the material deposited by the scow. Each ofthese pumps has a discharge-pipeff, through which the material drawnfrom the vat is forced. These several pipes are so arranged as tocombine atsome convenient looality,preferably at the top of or above thedock,into a single discharge-pipe (not shown) which leads to the shoreand has its discharge end located. above lthe territory to be reclaimed.It is ofcourse to be understood that the positionot the outer end ofthedis' The various pumps G G are preferably oper# ated in successioninstead of simultaneously, asthereby the power required by the engine Dand motor F will only be that'required for a single pump. There need beno loss of time by this successive operation, because the intervalbetween the arrival of successive scows will be sufficient to empty allthe vats one at To accomplish this operation ofthe pumps G in sequence,they are arranged and mounted as follows: 'A driving-shaft a, journaledin suitable bearings secured upon the framework of thedock, runs alongthe line of pumps and carries a'. number of gear-wheels b b, which mesh,respectively, with the pumpgear c c. The gears b bjhowever, yare looseupon the shaft a, eachbeing accompanied by a clutch d, whichis'rsplinedupon the shaft d and which when brought in yconnection with itscorresponding gear turris the same and communicates,therotation of theshaft a. to

`the pump whichit is desired to operate. The

selection of the .pump to be operated is made by the engineer in charge,thepump being shut off as soon as its vat is emptyand alnew pumpstarted. Each pump is also provided with a valve e, by whichcommunication with avat is opened or closed.

IOO

Rotation is communicated to the shaft a from the motor F as follows: Themotor-shaft a', journaled in suitable bearings, carries a gear 7L, whichmeshes with an intermediate gearj, mounted upon a secondary shaft a?,journaled in the framework land carrying a gear l, which meshes with thegear m, keyed to the shaft a. It will thus be seen that the shaft a isin constant rotation during the operation ot' the motor F, but thatAthis rotation is communicated to the pumps only when one or more of theclutches d takes up its corresponding transmitting-gear.

The rotary pumps G G are of ordinary and usual construction and providedwith a suction-pipef', leading from the bottom of the trough C C. To aidthe suction of the mud and other heavy material deposited in thetroughs, I provide in the bottom of each vat the agitating and feedingchain p, which is kept in constant motion over the sprocketss, one anidle sprocket at the end of the trough and the other preferably mountedinside the suction-pipe on the shaft CL3, Fig. 3. This shaft carries thesplined clutches d and is turned positively by connection (not shown) bythe pump-gear o.

The operation of my land-reclaiming dock is as follows: A loaded scow isdrawn into the waterway B, so that its discharge-gates are immediatelyabove the receiving vats C. These gates are then tripped in the ordinaryway and the contents of the scow deposited in the vats. The seow isthenwithdrawn from the waterway and is towed back to the dredge orothersource of filling material. One of the pumps G is then set inoperation by bringing its corresponding clutch d into contact with itstransmitting-gear and continued in operation, sucking out the materialfrom the bottom of the vat through the pipe f and forcingit through thepipefinto the comm on discharge-pipe, by which itis carried and fromwhence it is delivered to the locality to be reclaimed. As soon as thesolid coutents oll one vat have been withdrawn the operation ol' itscorresponding pump is stopped and a new pump started by moving theproper clutch. This goes on until all the pumps have operated to emptytheir respective vats and the dock is ready to receive anotherscow-load.

The advantages of my apparatus will, I think, be readily understood, asby itI am not only able permanently to remove the material raised byharbor, river, or other dredges permanently from the water, but Iutilize this material in making new land.

I claiml. A land-reclaiming' dock adapted to be moored near the localityto be reclaimed and provided with a waterway which allows the passage ofscows or other vessels through vthe same, receiving channels or vatsarranged transversely thereunder and inclined toward the pump side, andsuitable pumping and conveying apparatus by which the dredged materialreceived from said scows or other vessels may be conveyed to ordeposited ou said locality substantially as described.

2. A land-reclaiming dock provided with a suitable waterway,receiving-vats thereunder, pumping and conveying apparatus, and astirring and agitating chain at the bottom of each vat and adapted tofeed the dredged material to the pump, substantially as described.
